Proteome profiling of ductal carcinoma in situ.

BACKGROUND AND AIM: DCIS is the most common type of non-invasive breast cancer, accounting for about 15 to 30%. Proteome profile is used to detect biomarkers in the tissues of breast cancer patients by mass spectrometry. This study aimed to obtain the expression profile of DCIS proteome, and the expression profile of invasive biomarkers, and finally to introduce a dedicated biomarker panel to facilitate the prognosis and early detection for in situ breast cancer patients. METHODS AND MATERIALS: In this study, 10 patients with breast cancer (DCIS) were studied. Benign (marginal) and cancerous tissue samples were obtained from patients for proteomics experiments. Initially, all tissue proteins were extracted using standard methods, and the proteins were separated using two-dimensional electrophoresis. Then, the expression amount of the extracted proteins was determined by ITRAQ. The data were analysed by R software, and gene ontology was utilised for describing the protein in detail. RESULTS: 30 spots on gel electrophoresis were found in the tumor tissue group (sample), and 15 spots in the margin group (control) with P < 0.05. Healthy and cancerous tissue gels showed that 5 spots had different expression. VWF, MMP9, ITGAM, MPO and PLG protein spots were identified using the site www.ebi.ac.uk/IPI. Finally, protein biomarkers for breast tumor tissue with margin were introduced with the names of P04406, P49915, P05323, P06733, and P02768. DISCUSSION: There are 5 critical proteins in inducing cancer pathways especially complement and coagulation cascades. The hall markers of a healthy cell to be cancerous are proliferation, invasion, angiogenesis, and changes in the immune system. Hence, regulation of protein plays a key role in developing recurrence to breast cancer in margins.

The Effect of Educational Intervention on Nurses' Attitudes Toward the Importance of Family-Centered Care in Pediatric Wards in Iran.

INTRODUCTION: Family-centered care sustains the unity of the child's and the family's health. The aim of this study was to determine nurses' attitudes toward parents' participation in the care of their hospitalized children in Iran in 2015. METHODS: In this experimental study, 200 pediatric nurses from hospitals affiliated with the Shaheed Beheshti University of Medical Sciences in Tehran were selected using the multi-stage, random-sampling method. Data were gathered using a questionnaire that covered demographic information and nurses' attitudes. The questionnaire consisted of 31 items and was completed by the nurses in three stages: 1) before intervention (pre-test), 2) immediately after intervention (post-test), and 3) three months after intervention (follow-up). The data were analyzed via SPSS software and using descriptive and analytical methods. Descriptive statistics, the Spearman Correlation Coefficient, and Repeated Measure Analysis (the Bonferroni method) were used to assess the data. RESULTS: The results indicated that there was a significant increase in the mean score of attitude after intervention [M (pre) = 3.35%, M (post) = 3.97%, p < 0.001)]. Most of subjects had neutral attitudes toward family participation in their children's care. There were no significant relationship between the nurses' socio-demographic characteristics and their attitudes. CONCLUSION: The nurses' attitudes toward the family's participation in the care of their hospitalized children were moderate. The nurses' attitudes should be improved by taking part in continuous training programs.

Effects of family-centered care on the satisfaction of parents of children hospitalized in pediatric wards in a pediatric ward in Chaloos in 2012.

BACKGROUND: Family-centered care (FCC) involves holistic care and requires cooperation with the family in planning, intervention, and the evolution of the care that is being provided. Many previous studies have provided results that indicate the importance of the family's involvement in pediatric care, but there is still resistance in doing so within the organizational culture of the hospitals in Iran. The aim of this study was to determine the effects of FCC on the satisfaction of parents of children hospitalized in 2012 in the pediatric ward at Razi Hospital in Chaloos, Iran. METHODS: This Quasi-experimental study was conducted in 2012 in the pediatric ward at Razi Hospital in Chaloos, Iran. Seventy hospitalized children between the ages of 1 and 3 who suffered from diarrhea, vomiting, or pneumonia were selected through convenience sampling. They were divided randomly into two equal groups, a control group (routine care) and an experimental group (family-centered care). SPSS Statistics 14 software was used to analyze the data, and p<0.05 was considered to be significant. RESULTS: In the FCC group, the mean score of satisfaction among the parents of the children was 20 out of 90 before the intervention, but, after the FCC method was used, it increased to 83.2 out of 90. In addition, a significant difference was found between the scores of satisfaction for the control and experimental groups (p<0.001), and all parents of children in the experimental group expressed high satisfaction. CONCLUSION: Our findings showed that the practice of FCC in caring for the sick children can increase the satisfaction of their parents significantly. The role of the family's involvement is critical in every component of the intervention efforts, as shown by the constructs of participatory support, educational support, and psychological support. Thus, a notable implication here is that FCC may lead to increased quality of care and should be included in the educational programs of the nursing staff in pediatric ward.

Canthaxanthin biosynthesis by Dietzia natronolimnaea HS-1: effects of inoculation and aeration rate.

The interest in production of natural colorants by microbial fermentation has been currently increased. The effects of D-glucose concentration (3.18-36.82 g/L), inoculum size (12.5 × 10(9)-49.5 × 10(9) cfu cells/mL) and air-flow rate (1.95-12.05 L/L min) on the biomass, total carotenoid and canthaxanthin (CTX) accumulation of Dietzia natronolimnaea HS-1 in a batch bioreactor was scrutinized using a response surface methodology-central composite rotatable design (RSM-CCRD). Second-order polynomial models with high R (2) values ranging from 0.978 to 0.990 were developed for the studied responses using multiple linear regression analysis. The models showed the maximum cumulative amounts of biomass (7.85 g/L), total carotenoid (5.48 mg/L) and CTX (4.99 mg/L) could be achieved at 23.38 g/L of D-glucose, 31.2 × 10(9) cfu cells/mL of inoculation intensity and air-flow rate of 7.85 L/L min. The predicted values for optimum conditions were in good agreement with experimental data.
